TANDElVI-SPRING DRAFT-RIGGING FOR RAILWAY-CARS.

Specification of Letters Patent.

' iication.

Uur invention relates to tandem spring draft rigging for railway cars.

The object vof our invention is to provide a tandem spring draft riggingof a strong, simple, efficient and durable construction, and in whichthe side plates or stop castings shall be anchored to and combined withthe car framework in a very firm, safe and secure manner.

Uur invention consists in the means we employ and herein shown anddescribed for practically accomplishing this result, as moreparticularly set forth in the claims.

In the accompanying drawing forming a part of this specification, Figurel is a side elevation partly in central vertical section,

` of a tandem spring draft rigging embodying our invention. Fig. 2 is aplan view partly in horizontal section. Figs. 3, i and 5 are verticalcross sections on the lines 3 3, 4ta'- and 5*5 respectively of Fig. 2.Fig. 6 is a detail plan view of one of the tieplates. Fig. 7 is a detailperspective View of one of the side plates or stop castings.

In the drawing, A A represent the center sills or draft timbers or otherlongitudinal frame members of the car to which the draft rigging isdirectly applied, A1 the front or end sill, A2 the buffer block and A3is a transversely extending abutment or member of the car frame at therear of the draft rigging.

B is the draw-bar and B1 the draw-bar strap or yoke secured to thedraw-bar by rivets and interengaging lugs or shoulders l b2 on thedraw-bar. The draw-bar strap is furnished with a middle abutment blockb3 having curved faces bt to engage the middle followers and secured inplace by rivets b5. At its rear end the draw-bar yoke B1 is furnishedwith a curved loop Z9@ and a semi-cylindric filler block 57 to abutagainst the rear follower. and which is secured in place by a rivet bs.

C, C1 are tandem arranged. springs between tlie followers E El E2 E3.

D D are the side. plates or stop castings furnished with stops orshoulders d l1 d2 cl3 for the followers to abut against, andintermediate stops or shoulders Z4 Z5 Z6 Z7 to limit the compression ofthe springs by engagement with the followers. Each of the side plates orstop castings D has a forward outwardly inclined extension Z8 extendingto the extreme front end of the car framework where it is provided witha lateral flange dg flush with the upright front face ofthe abutmentblock A2. Each of the side plates or stop castings D is also furnishedwith an integral rearward extension d10 having a right angle foot orflange Zu abutting against a shoulder a on the rear transverse frame orabutment member A3. Each of the side plates or stop castings D is alsoprovided with upper and lower outwardly extending iianges c 12 and d,thus giving the side plate or stop casting a general channel form incross section, while its inner face is left free from upper and lowerflanges and substantially straight or smooth, excepting for the jogs,convolutions or bends which form the several stops and intermediatestops.

To afford an additional anchorage of the side plates or stop castings tothe car frame, each of thev side plates or stop castings D is furnishedwith an integral upwardly projecting abutment ZM which fits against thefront end of the longitudinal car frame sill or member A and in asuitable notch or recess al in the end or front sill A1.

The upper horizontal iange d of the outwardly flanged or channel shapedstop casting D fits under and abuts against the lower horizontal face ofthe car frame members A A1 and is secured thereto and to the bufferblock A2 by vertical bolts F.

G G are also removable guides secured to the side plates or stopcastings D by bolts g and upon which the followers rest and reciprocate.

H Il are tie plates extending between and secured to the side plates orstop castings D. These tie plates H are secured in place by bolts itextending through the horizontal iiange (Z13 of the side casting. Eachor these tie plates H is furnished with a central longitudinal guide orchannel h1 for the lower member of the draw-bar strap or yoke B1 to itand reciprocate in, and is provided at its outer ends with seats h2 toreceive the lower horizontal flanges @Z13 of 1 the channel shaped stopcastings D and with shoulders h3 for the outer edges of said flanges Z13to abut against. The tie plates H are secured to the lower horizontalflanges (Z13 of the stop castings D by removable bolts h having threadednuts h5 and keys he.

The longitudinal frame members A A of the car to which the side platesor stop castings D are secured are placed closer together than thelength of the followers so that the ends of the followers will projectunder these longitudinal frame members of the car and render unnecessaryany upper guide flange for the followers on the side plates or stopcastings D, thus materially simplifying their construction.

H1 H2 are rear upper and lower reinforcement plates extending betweenand firmly secured to the upper Y and lower flanges CX12 Z13 of the stopcastings D by rivets L7. And H3 H4 are front upper tie plates secured tothe upper flanges dm of the stop castings D by vrivets it?, the tieplate H4f having an upright integral flange H5.

H6 is the front carry iron supported by the bolts its.

The inner upright faces of the stop castings D, it will be seen fromFig. 7 of the drawing, are substantially straight and smooth except forthe upright recesses D1 therein to receive the ends of the followers.And, as will be seen from Fig. 2, these recesses D1 and the stopshoulders d d1 cl2 Z1 (Z4 d5 d and Z7 are formed by simple bends inthe-main upright web D3 of the stop casting. This gives the stop castingan exceedingly simple, strong and effective form free from projectionsor flanges on its inner face and of a substantially channel form incross section at all parts of its length.

'We claim 1. In a tandem spring draft rigging, the combination with thedraw-bar, draw-bar yoke, tandem arranged springs and followers, of.outwardly turned, channel shaped stop castings, each furnished withtransverse bends in the main, upright web thereof forming stops for thefollowers to abut against, said web being also provided with furthertransverse bends forming intermediate stops for the followers to abutagainst to limit the compression of the springs, the vertical faces ofall the bent out portions of the web and of the intervening portionsbetween the bent out portions being flat and unbroken, and the uprightrecesses intervening between the stops extending entirely across thestop casting from the upper to the lower face thereof and adapted toreceive the followers, the castings being secured to the under sides ofthe draft sills of the car by bolts extending through the upper flangesonly of the castings, substantially as specified.

2. As an article of manufacture, a stop casting for railway draftrigging, the said stop casting comprising a channel-shaped member, theflanges of which are arranged to be turned outwardly when applied inposition, said channel-shaped member being furnished with transversebends in the main upright web thereof forming stops for the followers toabut against with intervening upright recesses extending across saidmember from the upper to the lower face thereof, said recesses beingarranged to receive the followers, and the flanges of saidchannel-shaped member being entirely to one side of the main web thereofand the stop portions to the other side of the main web, substantiallyas specified.

3. As an article of manufacture, a stop casting for railway draftriggings which comprises a channel-shaped member, the flanges of whichare arranged to be turned outwardly when said member is applied inposition, said member being furnished with transverse bends in the mainupright web thereof forming stops for the followers to abut against withintervening upright recesses extending across said member from the upperto the lower faces thereof, said recesses being adapted to receive thefollowers, the flanges of said member being located entirely to one sideof the main web and the stop portions to the other side of the main web,said member being provided with a forward extension having a laterallyextending lange adapted to lie flush with the front face of thecar-frame work, said member being also provided with a rearwardextension adapted to abut against the transverse member of the car-frameat the rear of the draft rigging, substantially as specified.
